ENGINE AND GEAR CASING.

SPECIFICATION forming part of Letters Patent No. 772,214, dated October 11, 1904.

Application filed February 11, 1904. Serial No. 193,172. (No model.)

To all whom, it may concern:

Be it known that LJoHN OARNEY,a citizen of the United States, residing at Waltham, in the county of Middlesex and State of Massachu setts, have invented certain new and useful Improvements in Engine and Gear (lasing; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in casings for the engine and gearing of automobiles and the like.

The object of the invention is to provide a casing for this purpose which will protect the parts covered thereby from dust, dirt, or any foreign matter which would interfere with the perfect working of the parts.

Another object is to provide a casing for this purpose the connections of which will permit the parts to yield with the movement of the gearing and which will not rattle when jarred by the motion of the machine.

A further object is to provide a case of this character formed in separate sections for covering the difl erent parts of the gearing and engine, each section of which may be removed without disturbing the other parts.

With these and other objects in view the invention consists of certain novel features of construction, combinatiomand arrangement of parts, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a side elevation ofthe complete casing,'showing the arrangement of the connected sections. Fig. 2 is a longitudinal vertical sectional view of the same. Fig. 3 is a side elevation showing the sections detached. Fig. 4 is a detail vertical sectional view through the meeting edges of the engine and the chain-casing, showing the manner of fastening the two together.

Referring more particularly to the drawings, 1 denotes the casing, which is preferably constructed of leather and in three parts to wit, an engine-case 2, a sprocket-chain case 3, and a sprocket-wheel case 4. The engine case 2 consists of a leather covering which preferably conforms somewhat to the shape of the engine and is supported by straps 3' to a'fixed part of the frame which supports the engine. The front side of the engine-case is open, and in front of the same is arranged a curtain 2', of leather or other suitable material. In the side of the casing are formed openings 5, through which the engine may be oiled. These openings are normally closed by pivoted cover-plates 5. The rear side or end of the engine-casing where the chain-covering connects is left open to permit the passage of the sprocket-chain from the drivewheel on the engine to the sprocket-wheel on the axle, and in the sides of the engine-casing adjacent to this opening are formed a series of horizontally-disposed parallel slots 6'.

The chain-covering consists of a tapering open-ended case 8, the top or upper wall of which is removably secured to the side walls by strap and buckle connections 7. 4 The smaller end of the casing 3 is adapted to be inserted into the chain-opening of the enginecasing, and the sides of the same are provided with a series of laterallyprojecting studs 8, in which are formed openings or eyes 9. These studs 8 are adapted to engage and pass through the slots 6 in the sides of the engine-casing, after which a pin 10 is inserted through the eyes or openings 9 in the studs 8, thereby securing the end of the chain-casing with the engine-casing, the slots 6 permitting a slight play between the two casings to compensate for the movement of the gearing.

In the sides of the casing, at the large end of the same, are formed alined semicircular recesses 12, which allow for the passage of the Vehicle-axle. To the sides of the chaincasing above and below the recesses 12 are secured straps 13. To the end of the bottom of the chain-casing is secured a flap 14:, on the end of which is fixed a strap 15. In-the ends of the side walls of this casing, near thelower edges of the same, are formed slots 16.

The sprocket-wheel covering consists of a segmental-shaped casing 4, the flat side 4! of which is open and adapted to fit within the larger open end of the chain-casing and is held in place therein by means of the straps 13, which engage buckles 17 on the sides of the sprocket-casing, and by a strap 15, which engages a buckle 18 on the outer edge of said casing and holds the flap 14 up against the under side of the casing, as shown.

In the side walls of the sprocket-casing are formed centrally-disposed alined holes 19 to brace-rods.

In constructing acasing as herein described of independent sections it will be seen that any one of the same may be removed without removing the others and that, if so desired, only a part of the sections need be used. For instance, an engine may bealready provided with acasing, in which event simply the chain and sprocket-wheel casings would be used.

In forming the casings of leather or similar flexible fabric all noise which would be occasioned by the shaking or rattling of the parts if constructed of metal will be obviated. Furthermore, the parts of the casing when formed of leather may be readily cut and made to fit various formations in the construction of the engine and gearing, and while a form of casing is shown in the drawings for a particular design of engine it is obvious that the shape of the casing may be altered to fit any form of engine and gearing that it may be desired to inclose.

an engine covering, a chain cover, and a sprocket-wheel covering, and means for removably connecting said coverings together to form a complete casing for said parts, substantially as described.

2. An engine and gear casing comprising independently-formed sections for covering an engine, a sprocket-chain and a sprocketwheel, means whereby said engine and chainsections are connected together to have a sliding engagement one with the other, means for removably connecting the opposite end of said chain-section with said sprocket-wheel section, substantially as described.

3. An engine-casing having an opening, a chain-casing adapted to enter said opening, and means for connecting the two casings together.

4. An engine-casing having an opening, the walls of which are provided with slots, a geareasing entering said opening and provided with lugs to project through said slots, and means for engaging the lugs to hold the same in engaged position.

5. An engine-casing having an opening, the walls of which are provided with slots, a chaincasing provided with studs to pass through said slots, and pins adapted to be passed through said studs to hold the two casings connected.

6. An engine-casing provided in its front and rear walls with openings, a closure for the front opening, a chain-casing entering the rear opening, and means for connecting the two casings together.

7. An engine-casing provided with an opening, a chain-casing open at each end and having one end inserted within the opening in the engine-casing, a gear-casing adapted to it within the opening in the opposite end of the chain-casing, the casings thus being telescopically connected, and means for detachably connecting the casings together.

In testimony whereof I have hereunto set my hand in presence of. two subscribing witnesses.

JOHN CARNEY.
